Hot Topic: Surfaces for Environment -Liquid Waste Treatment.

The immobilization of calixarenes onto inorganic materials of high specific surface area allows the selective separation of radionuclides from liquid nuclear waste solutions. A novel solid-liquid extraction method, called SOLIEX (Solid-Liquid Extraction), comprises the carbon felt modified with 1,3-alternate calix[4]arene-crown-6 conformer acting like a sieve to filter the radionuclides, notably cesium and strontium.
